The integrated safety management system according to an embodiment of the present invention may include a plurality of sensor beacons 100, a beacon reader 200, a safety band 300, and an integrated safety management server 400.

The sensor beacon 100 functions as a beacon that wirelessly transmits the function of the sensor for measuring the concentration of the surrounding gas, the gas concentration sensing value measured through the sensor, and the identification information (ID) of the sensor beacon 100 itself .

The sensor beacon 100 may include a semiconductor type gas detection sensor or an electrochemical gas detection sensor.

The semiconductor type gas detection sensor can measure the gas concentration by using the change of the electric conductivity generated when the gas particles come into contact with the surface of the ceramic semiconductor. The electrochemical sensor can detect the gas concentration by the oxidation and reduction reaction The gas concentration can be measured through the magnitude of the current generated. However, the gas detection sensor included in the sensor beacon 100 of the present invention is not limited to these systems, and may be configured with various types of gas detection sensors used in industry.

The type of gas whose concentration is measured by the sensor beacon 100 includes oxygen, carbon monoxide, hydrogen sulfide, sulfur dioxide, hydrogen, ammonia, chlorine, hydrogen chloride, hydrogen cyanide, ozone, nitrogen monoxide, nitrogen dioxide, hydrogen fluoride, silane, Butane and the like.

A plurality of sensor beacons 100 may be installed in the factory, and each sensor beacon 100 may perform sensing for different gas types. The type of gas whose concentration is to be measured in the factory may vary depending on the process being performed in each zone in the factory and may vary depending on the process performed at the installation location of the sensor beacon 100, The types of detection sensors may be different.

That is, one sensor beacon 100 may include a plurality of types of detection sensors, and the types of the detection sensors included in each sensor beacon 100 may be different from that of the gas to be detected at the position where the sensor beacon 100 is installed It can be different depending on the kind.

The sensor beacon 100 can perform wireless short-range communication based on the Bluetooth technology through the beacon function. Specifically, the plurality of sensor beacons 100 disclosed in the present invention can perform communication based on a BLE mesh communication protocol. Bluetooth Low Energy (BLE) is a technology that allows Bluetooth devices to operate at lower power levels by reducing packet size, reducing the number of channels, simplifying device connection procedures, and reducing operating cycles compared to conventional Bluetooth technology. Mesh communication is a communication method in which existing Bluetooth devices communicate with each other in a short distance, one-to-one, one-to-many, so that data can be exchanged between Bluetooth devices.

The beacon reader 200 may receive the sensed value of the gas concentration from the plurality of sensor beacons 100 and transmit the sensing value to the integrated safety management server 400.

According to one embodiment, the beacon reader 200 can receive signals from a plurality of sensor beacons 100 through a BLE communication scheme. Also, the beacon reader 200 can perform communication with the integrated safety management server 400 through a communication method such as Wireless Fidelity (Wifi), Local Area Network (LAN), and BLE.

The safety band 300 is a kind of wearable device worn by the user and can communicate with the sensor beacon 100 and communicates with the integrated safety management server 400 through the beacon reader 200. [ Can be performed. Also, the safety band 300 can display the gas concentration sensing value and the evacuation information, etc. in the presence of the display unit.

The safety band 300 may receive the sensing value of the gas concentration and identification information of the sensor beacon 100 from the sensor beacon 100 via BLE communication. In addition, the safety band 300 may transmit the received information to the integrated safety management server 400 through the beacon reader 200.

According to one embodiment, the safety band 300 may include a function of checking biometric information such as a wearer's heart rate, body temperature, etc., and may transmit the biometric information to the integrated safety management server 400.

On the safety band 300, there may be an emergency button that a user wearing the safety band 300 can activate through a touch. When the user touches the emergency button, the safety band 300 can transmit an emergency signal to the integrated safety management server 400, thereby allowing the integrated safety management server 400 to perform an in-factory evacuation command.

The integrated safety management server 400 may analyze various information received from the sensor beacon 100 and the safety band 300. The integrated safety management server 400 may communicate with the sensor beacon 100 and the safety band 300 via the beacon reader 200. [

The integrated safety management server 400 can collectively perform safety management in the plant through analysis of the sensing value of the gas concentration detected by the sensor beacon 100. [

Basically, the integrated safety management server 400 can perform the evacuation notification in the factory when the sensing value of the specific gas concentration deviates from the reference range by comparing the sensing range with the reference range set for each gas type. In this case, the integrated safety management server 400 determines whether the sensing value of the gas concentration outside the reference range is received from the installed sensor beacon 100, and notifies the integrated safety management server 400 of the evacuation notification to a certain area including the location have.

The integrated safety management server 400 can manage the reference range for each gas type. For example, the oxygen concentration in the plant may be set within the reference range between 19.5% and 23.5%, and the reference range for the noxious gas concentration may be set to TWA, STEL, or the like.

Time Weighted Average (TWA) is the time-weighted average exposure standard, which means 8 hours per day, multiplied by the time of occurrence of the hazardous gas measured in 8 hours of operation per day. STEL (Short Term Exposure Limit) This means that if the worker is exposed to noxious gas for 15 minutes at a time, less than this standard, exposure of up to 4 times a day may be allowed if the exposure interval is more than 1 hour.

For example, the TWA for hydrochloric acid in the plant may be set at 1 ppm, and the STEL may be set at 2 ppm. In this case, a worker in the plant where the integrated management system is operated can work for 8 hours in an environment with a hydrochloric acid concentration of 1 ppm or less. If the concentration of hydrochloric acid increases to 2 ppm, the worker can work within 15 minutes.

In addition, the integrated safety management server 400 can transmit an evacuation command to the safety band 300 based on the user's heart rate and body temperature information received from the safety band 300, And can perform the evacuation command in a predetermined area including the position of the safety band 300. [

FIG. 2 is a table showing types of gases and exposure standards for which concentration is measured in the integrated safety management system according to an embodiment of the present invention. FIG.

2, the gas that can be detected by the sensor beacons 100 of the present invention can be classified into a category of a combustible gas, a toxic gas, a pyrophoric gas, and the like. As shown in FIG. Also, the sensor beacon 100 can detect the concentration of oxygen or the like, not the noxious gas.

Each sensor beacon 100 can detect a sensing value of the gas concentration in parts per million (ppm), and the sensed value is transmitted to the safety band 300 or the integrated safety management server 400, Can be used to analyze whether or not the concentration of the sample meets the safety standards such as TWA and STEL.

FIG. 2 shows the TWA and STEL standards for each gas type. The STEL, which is a short-time exposure standard, can be set higher than the TWA, which is a time-weighted average exposure standard. In addition, the STEL may not be set for a short-term exposure if the short-term exposure is a gas that can cause catastrophic damage to workers in the plant.

FIG. 3 is a diagram illustrating a path in which sensor beacons 100 perform communication according to an embodiment of the present invention.

Referring to FIG. 3, a plurality of sensor beacons 100 may be installed at a predetermined distance in a factory. According to an embodiment of the present invention, the sensor beacons 100 may communicate with each other through a BLE communication method. The distance that one sensor beacon 100 can perform wireless communication is a sensor beacon 100 ). ≪ / RTI > Since the BLE communication method is a communication method developed to save power, the communication range of the sensor beacon 100 can be limited to a shorter range than the conventional Bluetooth communication method.

As shown in FIG. 3, one sensor beacon 100 can communicate directly with only the sensor beacons 100 located within a certain distance from the sensor beacon 100, Or indirectly via the network 100. [

In this manner, by arranging the positions of the sensor beacons 100 so that the communication paths of the plurality of sensor beacons 100 constitute a mesh network configured as a net, 100 may reach the beacon reader 200. [

The factory entry permitting unit 370 analyzes the biometric information such as the heart rate and the body temperature of the user wearing the same through the safety band 300. If it is determined that the user's body condition is not normal, .

The factory entry permitting section 370 can permit the factory entry only when the air condition inside the factory is judged to be safe, through the sensing value of the gas concentration in the factory received while the user watches the safety education.

The emergency condition determination unit 380 can determine whether an emergency situation occurs by comparing the sensing value of the gas concentration received from the sensor beacons 100 with the exposure standard which is a reference range determined according to the gas.

The emergency state determination unit 380 may operate in a similar manner to the emergency state determination method of the integrated safety management server 400, which will be described later.

If the emergency situation notification unit 390 determines that the emergency situation has occurred by the emergency situation determination unit 380, the emergency state notification unit 390 can execute the evacuation command to the user. The emergency status notification unit 390 can control the evacuation command to be turned on in the display unit 310 as described above and can perform the evacuation command through the vibration and the alarm sound generated in the safety band 300 itself .

According to one embodiment, when the evacuation command is performed through the safety band 300, the path to evacuate may be displayed on the display unit 310. [ According to one embodiment, the evacuation route may be displayed on the map, and according to another embodiment, it may be displayed in the form of text, such as " evacuate toward the first exit. &Quot; The evacuation path information may be analyzed by the integrated safety management server 400 and transmitted to the safety band 300.

The safety band 300 may further include a communication unit for performing communication with the sensor beacon 100 and the beacon reader 200, a memory for storing information necessary for operation, a central processing unit such as a CPU for performing various operations required for the operation, Devices, and the like.

The communication unit allows the gas concentration sensing value receiving unit 360 to receive sensing values for various gas concentrations from the sensor beacons 100. [ The manner in which the communication unit performs communication with the sensor beacon 100 may be a BLE communication method. Also, the communication unit may communicate with the integrated safety management server 400 through the beacon reader 200, and the communication between the communication unit and the beacon reader 200 may be a BLE communication scheme.

6 is a block diagram illustrating an internal configuration of the integrated safety management server 400 according to an embodiment of the present invention.

6, the integrated safety management server 400 includes a gas concentration sensing value reception unit 410, a safety band signal reception unit 420, an emergency status determination unit 430, a gas leakage position determination unit 440, A sensor beacon management unit 460, a control unit 470, and a communication unit 480. The communication unit 480 may be a wireless communication unit.

The gas concentration sensing value receiving unit 410 may receive sensing values of various kinds of gas concentrations and identification information of each sensor beacons 100 from a plurality of sensor beacons 100. [ Also, the gas concentration sensing value receiving unit 410 may receive the sensing value and the identification information through the safety band 300. [

The safety band signal receiving unit 420 may receive various signals transmitted from the safety band 300. The safety band signal receiving unit 420 can receive the emergency signal transmitted by touching the emergency button located in the safety band 300 by the user.

The safety band signal receiving unit 420 can receive the heart rate and the body temperature information of the user wearing the safety band 300 at predetermined time intervals and when the user's heart rate and body temperature are out of the predetermined reference value, It is also possible to receive an emergency signal.

The emergency status determiner 430 may determine whether an emergency situation has occurred in the factory through the information received through the gas concentration sensing value receiver 410 and the safety band signal receiver 420. [

Specifically, the emergency situation determination unit 430 can determine the emergency situation of the entire factory through the gas concentration sensing value, and can determine the safety band of the factory through the user's heart rate and body temperature measured by the safety band 300, It is possible to determine an emergency situation for the wearer.

The emergency situation determination unit 430 determines whether or not the sensed value of the gas concentration detected by the sensor beacon 100 corresponds to the sensed value of the gas concentration detected by the sensor beacon 100, It can be judged whether or not it is out of the reference range for gas.

As shown in FIG. 2, a reference range for the gas mainly detected in the factory is determined, and the emergency condition determiner 430 can determine whether an emergency situation has occurred in the factory through the reference range.

For example, when the TWA for ozone is set to 0.08ppm and the STEL is set to 0.2ppm, if the criterion for determining the emergency situation is set to the strictest, the emergency condition determiner 430 determines that the ozone concentration If the sensing value is measured as 0.08 ppm or more, it can be judged as an emergency situation. The STEL value, which is a short-time exposure criterion, does not affect the judgment of an emergency situation under such a strict judgment criterion because the STEL value as the short-time exposure standard is always set higher than the TWA value as the time-weighted average exposure standard.

If the severity of the criterion for determining the emergency situation is lowered, the emergency situation determiner 430 determines that the average of the gas concentration sensing values measured for a predetermined period of time is higher than the TWA value If the concentration of the specific gas is higher than the TWA value and remains lower than the STEL value for more than 15 minutes, the STEL value may be judged to be an emergency situation.

The emergency situation determination unit 430 receives information on the heart rate, body temperature, and the like, which is biometric information of the user wearing the safety band 300, from the safety band 300 and can determine the emergency situation through the information.

For example, if the user's heart rate or body temperature continues to increase for a predetermined period of time, the emergency-state determining unit 430 may determine the emergency state. In addition, the emergency status determiner 430 may store body condition information of a user wearing the safety band 300, and may set different emergency status determination criteria for each user.

According to one embodiment, the emergency status determiner 430 may receive an emergency signal from the safety band 300 and may determine that it is an emergency immediately. According to another embodiment, A message indicating that individual confirmation of the wearer of the safety band 300 which transmitted the emergency signal is necessary is checked in the integrated safety < RTI ID = 0.0 > To the manager of the management server 400. [

When the sensing value of the concentration of the specific noxious gas is detected to the extent that the sensed value is out of the reference range, the gas leakage position determination unit 440 can determine the point where the noxious gas flows out. Since a plurality of sensor beacons 100 are installed in the factory, a sensing value for a specific noxious gas concentration can be measured at a plurality of places where the sensor beacons 100 are installed. In addition, since the sensor beacons 100 transmit the identification information of the sensor beacon 100 itself together with the sensing value of the gas concentration, the integrated safety management server 400 determines the position of each sensing value of the gas concentration It can be confirmed whether or not it is transmitted from the installed sensor beacons 100.

The gas leakage position determination unit 440 can determine a leakage position of the noxious gas through the sensing value of the gas concentration received from the sensor beacons 100 and the position of the sensor beacons 100.

In detail, when it is determined that a specific noxious gas has leaked, the gas leakage position determiner 440 determines the leakage position of the sensor beacons 100 based on the positional relationship of the sensor beacons 100 having the highest sensed value of the noxious gas concentration Can be determined.

For example, the gas leakage position determination unit 440 may select three sensor beacons 100 having a high ammonia concentration sensing value when the concentration of ammonia in the factory is detected to be higher than a predetermined level, 100 can be determined to have a leaked position of ammonia gas within a triangular region formed by imaginary lines on the map. Further, even in the triangular region of the map, it may be determined that the ammonia gas has leaked at a position near the sensor beacon 100 in which the sensing value of the ammonia concentration is the highest.

In this way, the position of the gas leakage determined by the gas leakage position determination unit 440 can be displayed in a map form to the manager through the administrator terminal connected to the integrated safety management server 400, The repair team can also be mobilized to help prevent gas leaks.

If it is determined that there is no one remaining in the zone including the gas leakage position determined by the gas leakage position determination unit 440, the integrated safety management server 400 performs an operation such as lowering the shutter to close the corresponding zone It is possible. In addition, the integrated safety management server 400 can determine the place where the sensor beacon 100 should be additionally installed thereafter and display it to the manager of the integrated safety management server 400 through analysis of the determined gas leakage position have.

If the emergency situation determination unit 430 determines that an emergency situation has occurred in the factory, the evacuation command execution unit 450 may perform a evacuation command for the entire factory or a part of the factory. In detail, the evacuation command execution unit 450 can perform the evacuation command broadcasting through a speaker or the like installed in the factory, and can display a screen including the evacuation command on various display devices operating in the factory have. In addition, the evacuation command execution unit 450 may transmit the evacuation signal to the safety band 300 so that the safety band 300 informs the user of the evacuation command using the display, vibration, sound, etc. of the display unit.

According to one embodiment, the evacuation command execution unit 450 may specify the evacuation route in consideration of the gas leakage position determined by the gas leakage position determination unit 440, and perform the evacuation notification. For example, if there are three doors in the area where the noxious gas leakage has occurred, the evacuation command execution part 450 determines the position of the noxious gas leakage judged by the gas leakage position judging part 440 and the position of the most distant first Information to evacuate at the door can be propagated through the above-described methods.

The sensor beacon management unit 460 can manage the sensor beacons 100 installed in the factory.

The sensor beacon management unit 460 may periodically check the battery consumption of the sensor beacons 100. When it is determined that the battery of the specific sensor beacon 100 should be replaced, And displayed on the connected administrator terminal.

The sensor beacon management unit 460 can determine whether the sensor function of each sensor beacon 100 operates normally by comparing the gas concentration sensing values received from the sensor beacons 100. [ For example, if the sensed value of the noxious gas concentration detected in the specific sensor beacon 100 differs from the proximate sensor beacons 100 by a predetermined level or more, it is determined that a failure has occurred in the sensor function of the sensor beacon 100 can do.

The controller 470 includes a gas concentration sensing value receiving unit 410, a safety band signal receiving unit 420, an emergency status determination unit 430, a gas leakage position determination unit 440, a evacuation command execution unit 450 ), The sensor beacon management unit 460, and the communication unit 480. That is, the control unit 470 according to the present invention includes a gas concentration sensing value receiving unit 410, a safety band signal receiving unit 420, an emergency status determination unit 430, a gas leakage position determination unit 440, 450, the sensor beacon management unit 460, and the communication unit 480, respectively.

The communication unit 480 according to an embodiment enables communication between the integrated safety management server 400 and an external device. Specifically, the integrated safety management server 400 enables communication with the sensor beacons 100 and the safety band 300 via the beacon reader 200. [

7 is a flowchart illustrating an operation method of the safety band 300 according to an embodiment of the present invention.

Referring to FIG. 7, the safety band 300 may provide safety education to the user before entering the factory (S710). The safety training may be provided through the display unit included in the safety band 300, and may include different contents depending on the area of the factory where the user intends to enter.

Thereafter, the safety band 300 may determine whether the user has normally completed safety education (S720). If the user does not normally complete the safety training, the user's entrance to the factory may be disallowed, and if the user desires to enter the factory, he or she may need to watch the safety training again.

For example, when the user does not normally complete the safety training, when the user does not wear the safety band 300 and thus the heart rate and the body temperature are not measured, the user does not perform the operation of the safety band 300 required during the safety education A case where the safety band 300 is out of a predetermined distance from the factory door during the safety education viewing, and the like may exist.

Alternatively, if the user successfully completes the safety training through the safety band 300, the factory entry is permitted (S730).

After the user enters the factory through the above procedure, the safety band 300 may receive the sensing value of the gas concentration from the nearest sensor beacon 100 (S740). In detail, the safety band 300 receives sensing values of nearby communicatable sensor beacons 100, identifies the location of the sensor beacons 100 through identification information of the sensor beacons 100, , The sensor beacon 100 closest to the safety band 300 can be determined.

Thereafter, the safety band 300 compares the received sensed value with the predetermined exposure standard for each type of gas, and determines whether the received gas concentration sensing value exceeds the exposure standard (S750). The safety band 300 may analyze the change in the sensing value of each gas concentration received from the sensor beacon 100 according to the passage of time, It can be determined whether the sensing value of the gas concentration exceeds the exposure standard. Also, the safety band 300 may analyze the change in the sensing value of the gas concentration as described above. However, if the specific gas concentration is detected at a predetermined value or more, it is determined that the emergency band is an emergency situation .

If the sensing value of the specific gas concentration exceeds the exposure standard, the safety band 300 may determine that an emergency has occurred and deliver the evacuation command to the wearer of the safety band 300 (S760). The evacuation command may be issued through vibration, sound, lighting of the display unit, or the like, which occurs in the safety band 300.

FIG. 8 is a diagram illustrating a method by which the integrated safety management server 400 determines a noxious gas leakage position according to an embodiment of the present invention.

FIG. 8 shows a plurality of sensor beacons 100 installed in a specific area in the factory. Numbers indicated in each sensor beacon 100 represent sensing values for specific gas concentrations, and units of sensing values may be ppm.

Referring to FIG. 8, the integrated safety management server 400 may determine that the hazardous gas is in an emergency state when 3 ppm or more is detected. The integrated safety management server 400 determines the gas leakage position based on the sensing value received from each sensor beacon 100 when the integrated safety management server 400 receives the noxious gas concentration sensing value of 3 ppm or more as a reference value in at least one of the plurality of sensor beacons 100 can do.

In particular, the integrated safety management server 400 may determine the gas leakage location through the location of the sensor beacons 100 that received a higher sensing value. Although FIG. 8 shows an embodiment for determining the gas leakage position through the positional relationship of the three sensor beacons 100, the number of the sensor beacons 100 used for determining the gas leakage position is not limited thereto.

In FIG. 8, three sensor beacons 100 are selected in ascending order of sensing values for harmful gas concentrations, and the integrated safety management server 400 connects the positions of the selected sensor beacons 100 with imaginary lines It can be determined that a gas leakage position exists in the formed triangular region. In FIG. 8, the determined gas leakage positions are indicated by dots.

The integrated safety management server 400 can determine that a gas leakage position exists at a position close to the sensor beacon 100 having a high sensing value of the noxious gas concentration even in the area shown in a triangular shape in Fig. If the sensor beacons 100 measuring 3 ppm, 3.8 ppm and 3.3 ppm in FIG. 8 are referred to as first, second and third sensor beacons 100, respectively, the integrated safety management server 400 determines whether the first sensor beacon 100 100, the sensing value of the second and third sensor beacons 100 is greater than the sensing value of the first sensor beacon 100. Therefore, it can be determined that the gas leakage position exists at the lower end of the triangular region, 100, the sensing value of the second sensor beacon 100 is greater than the sensing value of the second sensor beacon 100, so that it can be determined that the gas leakage position exists at a position close to the second sensor beacon 100.

As described above, according to the embodiments of the present invention, safety education can be enforced to the user through the safety band 300 before entering the factory, and the safety band 300 can communicate with the sensor beacons 100 It is possible to evacuate the user by detecting an emergency situation.
